Floating-Point Registers: There are thirty-two floating-point registers, FR0–FR15 and XF0–
XF15. FR0–FR15 and XF0–XF15 can be assigned to either of two banks (FPR0_BANK0–
FPR15_BANK0 or FPR0_BANK1–FPR15_BANK1).
FR0–FR15 can be used as the eight registers DR0/2/4/6/8/10/12/14 (double-precision floating-
point registers, or pair registers) or the four registers FV0/4/8/12 (register vectors), while XF0–
XF15 can be used as the eight registers XD0/2/4/6/8/10/12/14 (register pairs) or register matrix
XMTRX.
Register values after a reset are shown in table 2.1.

Note:
The register configuration in each processor is shown in figure 2.2.
Switching between user mode and privileged mode is controlled by the processor mode bit (MD)
in the status register.
